Hello, followers of the cow. I've read that the -O3 gcc flag enables optimizations that basically fuck up. Now, i've saw exactly what those optimizations are and one is to do crazy inlining and other one is to use more registers on architectures with many registers (-frename-registers). So, since -03 by itself is said to be evil but -frename-registers should be advantageous on amd64 since it has some registers (at least more than x86 so I'm thinking it qualifies as good for the flag), anyone knows if 02 + -frename-registers is safe? I know that safe is a poorly defined word so let's say "safe so that it doesn't fuck up more than 1 application in 100". Hugs to everybody that follows Larry the cow.
